Product details
Overview
R5F5631MDGFM#H0 from Renesas is a 100 MHz 32-bit RX CPU core microcontroller in the RX631 Group, featuring 768 KB on-chip flash memory, 128 KB SRAM, 32 KB data flash, and integrated 12-bit/10-bit A/D converters. It supports USB 2.0 full-speed host/function interface, CAN (ISO 11898-1), up to 13 SCI channels, 4 I²C interfaces, and operates from a single 2.7–3.6 V supply across –40 to +85°C. It targets industrial HMI, motor control, and networked embedded systems requiring deterministic real-time performance without Ethernet.
For engineers reviewing the R5F5631MDGFM#H0 datasheet, R5F5631MDGFM#H0 pinout, R5F5631MDGFM#H0 application, or R5F5631MDGFM#H0 equivalent, this page delivers verified specifications, package mapping to PLQP0176KB-A (176-pin LQFP), confirmed peripheral channel counts per package, functional distinctions from RX63N (no Ethernet), and validated alternative MCUs for cost-optimized or feature-matched designs.
Technical Context
The R5F5631MDGFM#H0 implements the RXv1 CPU core with Harvard architecture, 5-stage pipeline, and variable-length instructions enabling ultra-compact code density. It integrates a memory protection unit (MPU), IEEE-754 single-precision FPU, and dual multiply-and-accumulate units - one optimized for register-to-register and another for memory-to-memory operations.
Its clock system includes internal 125 kHz LOCO and 50 MHz HOCO oscillators, external crystal support (4–16 MHz), and PLL-based frequency synthesis. Power management features four low-power modes, RTC battery backup capability, and module stop control - all coordinated via dedicated voltage detection and reset circuitry including POR and LVD.

The R5F5631MDGFM#H0 operates at a maximum frequency of 100 MHz using the 32-bit RXv1 CPU core. This core delivers 165 DMIPS performance and includes a 5-stage pipeline, variable-length instructions, and IEEE-754 single-precision floating-point unit - all essential for deterministic real-time control in industrial applications. The R5F5631MDGFM#H0 achieves zero-wait-state execution on both flash and SRAM at this speed.
Does the R5F5631MDGFM#H0 include an Ethernet controller?
No, the R5F5631MDGFM#H0 belongs to the RX631 Group, which explicitly excludes the Ethernet MAC and associated EDMAC peripheral present in the RX63N Group. This omission reduces silicon cost and power consumption while maintaining full USB 2.0 host/function, CAN, and multiple serial interfaces. Engineers selecting the R5F5631MDGFM#H0 should plan for external networking solutions if Ethernet is required.
What are the flash and RAM capacities of the R5F5631MDGFM#H0?
The R5F5631MDGFM#H0 integrates 768 KB of on-chip main flash memory and 128 KB of SRAM, both accessible at 100 MHz with zero wait states. It also includes 32 KB of reprogrammable data flash rated for 100,000 erase/write cycles - suitable for storing calibration data, firmware updates, or configuration parameters. These capacities are fixed for the R5F5631MDGFM#H0 and confirmed in Renesas document R01DS0098EJ0180.
Which package does the R5F5631MDGFM#H0 use, and what are its key mechanical attributes?
The R5F5631MDGFM#H0 uses the PLQP0176KB-A package: a 176-pin LQFP with 24 × 24 mm body size, 0.5 mm pin pitch, and exposed thermal pad. It is RoHS-compliant and designed for reflow soldering. This package supports all I/O functions specified for the RX631 Group in 176-pin configuration, including 133 general-purpose I/O pins with 5-V tolerance on 18 pins - critical for interfacing with legacy industrial sensors and actuators.
How does the R5F5631MDGFM#H0 support functional safety standards like IEC 60730?
The R5F5631MDGFM#H0 includes hardware features required for Class B compliance under IEC 60730: oscillation-stop detection, independent watchdog timer (IWDT), CRC calculator, self-diagnostic A/D converter test mode, and memory protection unit (MPU). These are documented in Renesas' RX63N/RX631 hardware manual and enable systematic fault detection without external components. The R5F5631MDGFM#H0 is qualified for industrial temperature range (–40 to +85°C), further supporting safety-critical deployment.
